I printed a PDF from Revit today, and was presented with this output:

The text was not printed from a linked DWG.

This problem resulted because:

  1. I linked a DWG into a Detail (Section) View
  2. I then rotated the Detail View in Plan.
  3. I moved the linked DWG back into position.
  4. But obviously Revit was not impressed with this course of events!

It was a relatively simple fix – I used Ctrl-X to ‘cut’ the DWG into nowhere, then pasted it back into the view, and also ‘reloaded’ the DWG from the Manage Links dialog.
